IIC 总线协议中文版本，对理解IIC很好用

前言 从接触STM32到现在，我感觉CAN通讯可以说是我学过的最难的一个章节了，由于本人也是从小白开始，所以我觉得学习的时候我们可能有很多相似的疑惑。正所谓感同身受嘛，就是难难难难，希望我的经验可以帮助更多人。 这篇博客是我用课余时间写的，前前后后的花了三天时间，加上代码总共1.6W多字，整理不易。内容有点多，如果一次看不完可以点赞收藏呀 物理层 与I2C,SPI等同步通讯方式不同，CAN通讯是异步通讯，也就是没有时钟信号线来保持信号接收同步，也就是所说的半双工，无法同时发送与接收，在同一时刻，只能有一个节点发送数据，其余节点都只能接收数据。它有CAN_HIGH与CAN_LOW两条信号线组成

CAN总线在ISO-11898 中的全集 ISO 11898-1:2003 specifies the data link layer (DLL) and physical signalling of the controller area network (CAN). This document describes the general architecture of CAN in terms of hierarchical layers according to the ISO reference model for open systems interconnection (OSI) established in ISO/IEC 7498-1 and provides the characteristics for setting up an interchange of digital information between modules implementing the CAN DLL with detailed specification of the logical link control (LLC) sublayer and medium access control (MAC) sublayer. ISO 11898-2:2003 specifies the high-speed (transmission rates of up to 1 Mbit/s) medium access unit (MAU), and some medium dependent interface (MDI) features (according to ISO 8802-3), which comprise the physical layer of the controller area network. ISO 11898-3:2006 specifies characteristics of setting up an interchange of digital information between electronic control units of road vehicles equipped with the CAN at transmission rates above 40 kBit/s up to 125 kBit/s. ISO 11898-4:2004 specifies time-triggered communication in the CAN. It is applicable to setting up a time-triggered interchange of digital information between electronic control units (ECU) of road vehicles equipped with CAN, and specifies the frame synchronisation entity that coordinates the operation of both logical link and media access controls in accordance with ISO 11898-1, to provide the time-triggered communication schedule. ISO 11898-5:2007 specifies the CAN physical layer for transmission rates up to 1 Mbit/s for use within road vehicles. It describes the medium access unit functions as well as some medium dependent interface features according to ISO 8802-2. This represents an extension of ISO 11898-2, dealing with new functionality for systems requiring low-power consumption features while there is no active bus communication.
